Removing the $ after dyn in the RewriteRule doesn't seem to do it. Can I hard code the "/?q=customer%20reference&f=1,1,1,1,1,1&c=10,10,10,10,10,10&s=1,1,1,1,1,1,1&st=1‌​" in the RewriteRule?

Not sure. Another problem is the $ after $f=1$ in RewriteCond. That means you only look for strings that end like that, and so won't match f=1,1,1,1, etc.
